Ok, I am confused by this. I am doing a school project on i/o with an address database. The professor gave us a template to work with, which saved me a few minutes.
The problem is I can enter information to the txt file fine. When I attempted to read it I get this error from VS2010 "Unhandled exception at 0x00cb3246 in LAB7.exe: 0xC0000005: Access violation reading location 0x00000014." Can someone take a look at my code and give me some direction?

In line number 37, 84, 85, you are declaring char userChoice= ' '. Instead try this char userChoice.
In line 94, you have a getline(cin, name); which I think should't be there.
Instead of spliting, try using ',' as delimiter in getline (myAddress, firstLine, '\n').
It will take all character that are before ','. Try out these first. I don't think that a separate spliting function is required.
